Under the Hunter's Moon' is a multi-level Single Player campaign based on the 20th Century Fox movie, 'Alien vs Predator' (2004) explored from the Perspective of one of the Predator initiates that enters the pyramid. The Campaign is structured to follow the events of the AvP movie up until the point where two young Predators are killed by the Alien known as 'Grid'. That event does not occur in this Campaign and an alternate narrative branches just prior to this incident.
You will be required to combat Humans and Aliens; and solve environmental obstacles and puzzles. Your goal is to complete specific Objectives in order to survive and finish the Campaign. You will then finally be acknowledged as worthy to join the the 'Brothers of the Spear' Clan as a fully fledged member of their Hunter caste.
